| 3 | The gut microbial metabolite, 3,4-dihydroxyphenylpropionic acid, alleviates hepatic ischemia/reperfusion injury via mitigation of macrophage pro-inflammatory activity in mice显示文摘Hepatic ischemia/reperfusion injury(HIRI) is a serious complication that occurs following shock and/or liver surgery. Gut microbiota and their metabolites are key upstream modulators of development of liver injury. Herein, we investigated the potential contribution of gut microbes to HIRI.Ischemia/reperfusion surgery was performed to establish a murine model of HIRI. 16 S r RNA gene sequencing and metabolomics were used for microbial analysis. Transcriptomics and proteomics analysis were employed to study the host cell responses. Our results establish HIRI was significantly increased when surgery occurred in the evening(ZT12, 20:00) when compared with the morning(ZT0, 08:00);however, antibiotic pretreatment reduced this diurnal variation. The abundance of a microbial metabolite3,4-dihydroxyphenylpropionic acid was significantly higher in ZT0 when compared with ZT12 in the gut and this compound significantly protected mice against HIRI. Furthermore, 3,4-dihydroxyphenylpropionic acid suppressed the macrophage pro-inflammatory response in vivo and in vitro. This metabolite inhibits histone deacetylase activity by reducing its phosphorylation. Histone deacetylase inhibition suppressed macrophage pro-inflammatory activation and diminished the diurnal variation of HIRI. Our findings revealed a novel protective microbial metabolite against HIRI in mice. The potential underlying mechanism was at least in part, via 3,4-dihydroxyphenylpropionic acid-dependent immune regulation and histone deacetylase(HDAC) inhibition in macrophages. | Rui Li Li Xie Lei Li Xiaojiao Chen Tong Yao Yuanxin Tian Qingping Li Kai Wang Chenyang Huang Cui Li Yifan Li Hongwei Zhou Neil Kaplowitz Yong Jiang Peng Chen | 2022 | Acta Pharmaceutica Sinica B2022，12，1： | 8 |
| 4 | Chemical compound cinobufotalin potently induces FOXO1-stimulated cisplatin sensitivity by antagonizing its binding partner MYH9显示文摘In this study,we present novel molecular mechanisms by which FOXO1 functions as a tumor suppressor to prevent the pathogenesis of nasopharyngeal carcinoma(NPC).First,we observed that FOXO1 not only controlled tumor stemness and metastasis,but also sensitized NPC cells to cisplatin(DDP)in vitro and in vivo.Mechanistic studies demonstrated that FOXO1-induced miR-200b expression through the GSK3β/β-catenin/TCF4 network-mediated stimulation of ZEB1,which reduced tumor stemness and the epithelial–mesenchymal transition(EMT)signal.Furthermore,we observed FOXO1 interaction with MYH9 and suppression of MYH9 expression by modulating the PI3K/AKT/c-Myc/P53/miR-133a-3p pathway.Decreased MYH9 expression not only reduced its interactions with GSK3β,but also attenuated TRAF6 expression,which then decreased the ubiquitin-mediated degradation of GSK3βprotein.Increased GSK3βexpression stimulated theβ-catenin/TCF4/ZEB1/miR-200b network,which increased the downstream tumor stemness and EMT signals.Subsequently,we observed that chemically synthesized cinobufotalin(CB)strongly increased FOXO1-induced DDP chemosensitivity by reducing MYH9 expression,and the reduction in MYH9 modulated GSK3β/β-catenin and its downstream tumor stemness and EMT signal in NPC.In clinical samples,the combination of low FOXO1 expression and high MYH9 expression indicated the worst overall survival rates.Our studies demonstrated that CB potently induced FOXO1-mediated DDP sensitivity by antagonizing its binding partner MYH9 to modulate tumor stemness in NPC. | YongHao Li Xiong Liu Xian Lin Menyang Zhao Yanyi Xiao Chen Liu Zixi Liang Zelong Lin Renhui Yi Zibo Tang Jiahao Liu Xin Li Qingping Jiang Libo Li Yinyin Xie Zhen Liu Weiyi Fang | 2019 | Signal Transduction and Targeted Therapy2019，4，1： | 6 |
| 5 | Prevalence of Metabolic Syndrome and Risk Factors Among Chinese Adults:Results from a Population-Based Study—Beijing,China,2017–2018显示文摘Summary What is already known about this topic?Metabolic syndrome(MetS)is one of the most easily available health indicative markers for cardiovascular diseases,and it has become a major public health problem worldwide due to increasing urbanization and aging populations.The prevalence of MetS increased dramatically in China,however,there are no records of MetS defined by the 2017 Chinese Diabetes Society for Beijing by far.What is added by this report?In this study,the data of 24,412 participants aged 18–74 years from a large population-based study in Beijing was collected.The overall prevalence of MetS among Beijing residents was 24.5%.The prevalence was 35.2%in males and 15.4%in females.What are the implications for public health practice?Effective public health strategies should target males,people with older age,lower education,higher body mass index,smokers,those who drink alcohol,those who are unemployed or retired,and those who live in rural areas on MetS prevention and control. | Jufen Liu Qingping Liu Zhiwen Li Jing Du Chao Wang Yanlin Gao Zaihua Wei Jing Wang Yunping Shi Jianting Su Yang Liu Ping Wang Chunyan Xie Gang Li Bing Shao Le Zhang | 2022 | China CDC weekly2022，4，29： | 4 |
| 6 | Electrospinning in membrane contactor:manufacturing Elec-PVDF/SiO2 superhydrophobic surface for efficient flue gas desulphurization applications显示文摘In membrane contactors,maintaining a high SO_(2)absorption flux and an excellent wetting resistance are crucial for hazardous gas removal.In this study,we adopted an electrospinning strategy to fabricate highly robust superhydrophobic dual-layer Elec-PVDF/SiO_(2)composite membrane contactors used for flue gas desulfurization.The composite membrane contactor consisted of a durable and ultrathin three-dimensional(3D)superhydrophobic surface and a porous supporting layer,where the formulation was optimized by regulating the PVDF concentration,solvent ratio and SiO_(2)particles content in electrospinning solution.The scanning electronic microscopy(SEM),EDS-mapping,water contact angle(WCA)and surface roughness of as-prepared Elec-PVDF/SiO_(2)composite membrane contactors were conducted to explore the physical and chemical structure.The SiO_(2)nanoparticles were uniformly loaded in ElecPVDF/SiO_(2)composite membrane contactor,and constructed micro-nano dual-coarse lotus-leaf-like morphology,which noticeably elevated surface roughness(Ra).The SiO_(2)nanoparticles also functioned as hydrophobic modifiers,which boosted the WAC up to 155.The SO_(2)absorption fluxes and SO_(2)removal efficiencies were investigated.In particular,the membrane contactor doped with 20 wt%SiO_(2)nanoparticles significantly elevated the stability of desulfurization performance.Besides,the membrane mass transfer coefficient(Km)and corresponding membrane mass transfer resistance(H/Km)were explored. | Qingping Xin Kaiqiang Xie Qingqing Liang Xu Li Yinan Zeng Yuhang Zhao Lei Zhang Shaofei Wang Hong Li Yuzhong Zhang | 2021 | Green Chemical Engineering2021，2，1： | 3 |
| 7 | Alteration of P2X3 expression in dorsal root ganglia after sciatic nerve ligation显示文摘BACKGROUND:The expressions of P2X3 receptor in dorsal root ganglia(DRG)after different peripheral nerve injuries are diverse.It indicates the different roles of P2X3 in different models-caused neuropathologic pains.OBJECTIVE:To observe the expressions of P2X3 in corresponding DRG after sciatic nerve ligation in rats.DESIGN:Controlled observation experiment.SETTING:Department of Morphology,Hunan Traditional Chinese Medical College;Department of Human Anatomy and Neurobiology,Xiangya Medical College,Central South University.MATERIALS:Thirty-five healthy adult SD rats of clean grade an d either gender,weighing(200±20)g,were involved.According to the random digits table,the involved rats were randomized into 3 groups:normal group(n =5),sham-operated group(n =5)and experimental group(n =25).The experimental group were subdivided into 3,7,14,21,28 days groups according to different surviving time after operation,5 rats at each time point.Polyclonal rabbit anti-P2X3 antibody(ABCAM company);biotinylated goat anti-rabbit IgG(Zhongshanjingqiao Biotechnical Co.,Ltd.,Beijing);Motic fluorescence microscope(Motic,Germany).METHODS:The experiments were carried out in the Department of Human Anatomy and Neurobiology,Xiangya Medical College,Central South University from June to December 2006.① Rats of experimental group were created into models by ligation of right sciatic nerve according to the method of Seltzer et al.Left sciatic nerve was used as self-control.As for rats in the sham-operated group,ligation of sciatic nerve was omitted,but other procedures were the same as those in the experimental group.Rats of normal group were untouched.② Rats of the normal group and sham-operated group survived for 14 days separately,and those of experimental group survived for corresponding time.After being deeply anesthetized by intraperitoneal injection of over-dose sodium pentobarbital,the rats of experimental group were transcardially perfused.L4-6 corresponding DRG connected to sciatic nerve were taken for preparing transverse sections serially.③P2X3 expression in L4-6 DRG was detected by immunohistochemistry,immunofluorescence and image analysis techniques.MAIN OUTCOME MEASURES:P2X3 expression in L4-6 DRG of rats in each group.RESULTS:Thirty-five SD rats were involved in the final analysis.① P2X3 expression in DRG:In normal DRG of rats,there were abundant P2X3 immuno-positive small-and medium-sized primary sensory neurons,especially the small ones,which mostly received the input from C fibers.There were only a few large neurons expressing P2X3.The immuno-positive products mostly were located in the cytoplasm and processes.The expression of P2X3 had a slight but significant decrease in ipsilateral L4-6 DRG 3 days after sciatic nerve ligation,and a decreasing tendency was observed with the elongation of time.At 28 days,the expression had not returned to base line,and still maintained at a low level.② P2X3 immuno-positive gray scale in DRG:P2X3 immuno-positive gray scale in ipsilateral side L4-6 DRG was 117.74±2.38,129.12± 4.86,133.56±3.79,148.75±6.90 and 150.49±5.15,respectively at 3,7,14,21 and 28 days after sciatic nerve ligation,which was significantly higher than that in the normal group and sham-operated group(105.11±3.52,104.22±5.41,F =78.861,P < 0.05),also significantly higher than that in the contralateral side(105.53±5.85,108.54±3.70,104.07±4.16,106.55±2.02,106.29±5.19,t =3.48-13.95,P < 0.05);There were no significant differences when comparing sham-operated group or contralateral side at each time point with normal group(P > 0.05)CONCLUSION:P2X3 is significantly down regulated in L4-6 DRG after sciatic nerve ligation.It may exert certain effects in neuropathic pain. | Guoxing Zhou Lesi Xie Qiben Wang Qingping Yu Xiaofu Liu Qiumei Liu Wei Peng Zhicheng Zeng | 2007 | Neural Regeneration Research2007，2，4： | 3 |

| 9 | Evidence for the role of KIF17 in fish spermatid reshaping:expression pattern of KIF17 in Larimichthys polyactis spermiogenesis显示文摘The homodimeric kinesin-2 protein KIF17 functions in intracellular transport and spermiogenesis in mammals.However,its role in fish spermiogenesis has not been reported.Here,we aimed to clone full-length kif17 cDNA and determine the molecular characteristics and expression patterns of KIF17 in Larimichthys polyactis spermiogenesis.The full-length cDNA of L.polyactis kif17(Lp-kif17)was sequenced and found to contain a 332-bp 5′untranslated region,480-bp 3′untranslated region,and 2433-bp open reading frame encoding 810 amino acids.Bioinformatics analyses showed that L.polyactis KIF17(Lp-KIF17)shared high sequence similarity with homologs in other animals and possessed an N-terminal motor domain with microtubule-binding sites and adenosine triphosphate(ATP)hydrolysis sites,a stalk domain containing two coiled-coil regions,and a C-terminal tail domain.The Lp-kif17 mRNA was widely expressed in various tissues,with the highest level in the brain,followed by that in the testis.Fluorescence in situ hybridization(FISH)analysis revealed that Lp-kif17 was continuously expressed in spermiogenesis,showing that it had potential functions in this process.Using immunofluorescence(IF)analysis,we found that Lp-KIF17 colocalized with tubulin and was transferred from the perinuclear cytoplasm to the side of spermatid where the tail forms during spermiogenesis.These findings suggested that KIF17 is involved in L.polyactis spermiogenesis.In particular,it may participate in nuclear shaping and tail formation by interacting with perinuclear microtubules during spermatid reshaping.In addition to providing evidence for the role of KIF17 in fish spermatid reshaping,this study provides important data for studies of reproductive biology in L.polyactis. | Jingqian WANG Xinming GAO Xuebin ZHENG Chen DU Congcong HOU Qingping XIE Bao LOU Feng LIU Shan JIN Junquan ZHU | 2021 | Journal of Oceanology and Limnology2021，39，6： | 1 |
| 10 | Maternal genetic history of southern East Asians over the past 12,000 years显示文摘Southern East Asia,including Guangxi and Fujian provinces in China,is home to diverse ethnic groups,languages,and cultures.Previous studies suggest a high complexity regarding population dynamics and the history of southern East Asians.However,large-scale genetic studies on ancient populations in this region are hindered by limited sample preservation.Here,using highly efficient DNA capture techniques,we obtain 48 complete mitochondrial genomes of individuals from Guangxi and Fujian in China and reconstruct their maternal genetic history over the past 12,000 years.We find a strong connection between southern East Asians dating to~12,000-6000 years ago and present-day Southeast Asians.In addition,stronger genetic affinities to northern East Asians are observed in historical southern East Asians than Neolithic southern East Asians,suggesting increased interactions between northern and southern East Asians over time.Overall,we reveal dynamic connections between ancient southern East Asians and populations located in surrounding regions,as well as a shift in maternal genetic structure within the populations over time. | Yalin Liu Tianyi Wang Xichao Wu Xuechun Fan Wei Wang Guangmao Xie Zhen Li Qingping Yang Peng Cao Ruowei Yang Feng Liu Qingyan Dai Xiaotian Feng Wanjing Ping Bo Miao Yun Wu Yichen Liu Qiaomei Fu | 2021 | Journal of Genetics and Genomics2021，48，10： | 1 |
| 11 | Enrichment characteristics and sources of the critical metal yttrium in Zhijin rare earth-containing phosphorites, Guizhou Province, China显示文摘Yttrium(Y)is a critical metallic element that is used widely in modern scientific,technological,and industrial applications.Phosphorites in the Zhijin area of Guizhou Province,China,are famous for Y enrichment,but the enrichment characteristics and sources remain unclear.Previous studies suggested that the sources of rare earth elements(REEs,La-Lu)and Y(REYs,La-Lu+Y)were related to hydrothermal deposition.However,this study presents evidence refuting that hypothesis,with major and trace elemental data collected with quadrupoleinductively coupled plasma-mass spectrometry(Q-ICPMS)analysis.These data show that Y in Zhijin REYscontaining phosphorites has a normal distribution and is particularly enriched relative to other REYs.The Y enrichment degree is different at different∑REY intervals.Specifically,the Y enrichment degree is higher at lower∑REY values and lower at higher∑REY values.The REYs-containing phosphorites show features of primary phosphorites.Both REEs and Y have good correlations with P2 O5 in the phosphorites with low REYs contents(total REYs<535 ppm),whereas at high REYs contents(total REYs>535 ppm),REEs have a good correlation with P2 O5 but Y does not.Inconsistent enrichment processes of REYs are suggestive of complex sources of Y.Thus,seafloor hydrothermal fluids were not the direct source of Y.Normal seawater mixed with terrestrial sources might have contributed to the origin of Y here.This study could lead to improvements in Y mineral resource explorations and the situation involving the global REYs supply crisis. | Xingxiang Gong Shengwei Wu Yong Xia Zhengwei Zhang Shan He Zhuojun Xie Jiafei Xiao Haiying Yang Qingping Tan Yi Huang Yuhong Yang | 2021 | Acta Geochimica2021，40，3： | 1 |

| 16 | Testis Development and Ultrastructural Features During Spermatogenesis in Cultured Small Yellow Croaker,Larimichthys polyactis显示文摘The small yellow croaker Larimichthys polyactis is an economically important marine fish in Northeast Asia.Currently,its natural resources are threatened by overfishing and environmental pollution.Therefore,research on the reproductive system of the fish is crucial.Here,we studied the testis development and ultrastructural features of spermatogenesis in cultured L.polyactis using anatomical,histological,and ultrastructural techniques.A pair of testes,consisting of a central sperm duct and radial seminiferous lobules,were observed.The reproduction cycle of testes can be divided into stages I–VI.March to May was confirmed as the breeding season for male L.polyactis,while April is the ideal period for artificial breeding.The male L.polyactis can attain sexual maturity within 1 year.The spermatogenesis of L.polyactis comprised spermatogonium,spermatocyte,spermatid,and mature spermatozoon.The morphology of spermatogenic cells changed obviously during spermiogenesis,including nuclear shaping,midpiece and flagellum formation.The mature sperms consist of an ellipsoidal head,a short midpiece,and a long flagellum.The anterior of the head with a kidney-shaped nucleus can be distinguished.The midpiece is located posterior to the head and includes four to six spherical mitochondria.The flagellum has irregular lateral fins.The testis of L.polyactis is an unrestricted lobular type,with cystic spermatogenesis,type II spermiogenesis,and type II spermatozoa.These features are highly similar to those of other Sciaenid species.Our findings provide useful insights into the mechanism underlying testis development and spermatogenesis of L.polyactis,which can facilitate the artificial breeding of this species. | ZHENG Xuebin WANG Jingqian GAO Xinming DU Chen HOU Congcong XIE Qingping LIU Feng ZHU Junquan LOU Bao | 2023 | Journal of Ocean University of China2023，22，5： | 0 |
